Homebrew glitched?

I had v3.4 on my wii. I followed the steps in 3.1 - 4.1 softmod guide. Unknowingly I installed preloader prior to upgrading to 4.1. Preloader loaded and I could get into the preloader menu, however it didn't work ("Couldn't find any hacks for system menu version v385") I found another thread here were someone had the same problem and was told to reinstall it. So i installed 4.1 upgrader. now I have v4.1 however I got two other problems: I can not boot into preloader like i use to could,... and the biggest problem is when I sign into the Homebrew channel I get a black screen and I have to power off the wii to reboot. Any help please....

Unknowingly means I thought it said I could skip that part...but now I know. And I have tried to reinstall HB but when I do I get this:
This installer can not continue.
There is known vulnerable IOS installed on this wii.
Please note that we willnot use a fakesigned IOS due to security reasions.
Look for updated verison at HTTP..//bootme.org
